End customer cannot use the Demo feature of the Parallels Presence Builder (PPB), when they open the URL like they see the following message:

Demo support is disabled

How can I enable the Demo feature on my PPB installation?


Follow the steps below to enable the Demo feature on the Parallels Presence Builder installation:

  1. Open the main configuration file of the PPB installation in text editor, use the Parallels Knowledgebase article #116634 to find the configuration file.

  2. Add the following line to the [general] section:

    demo_mode = 1

  3. Optionally, set the following parameters in the same section in the file (the default values are provided in the example below):

    • demo_max_file_size = 1048576 - maximal size of file which may be uploaded in demo mode (in bytes)
    • demo_max_file_count = 10 - maximal number of files which may be uploaded in demo mode
    • trial_site_life_time = 86400 - maximal lifetime of a trial site (in seconds)

PPB web interface language is defined by the localeCode in the GET-parameter, otherwise, if the parameter is undefined, the fallback_locale parameter in the configuration file is being used (e.g. fallback_locale = en_US).

When a customer opens URL like PPB creates trial site, web session and redirects the visitor to PPB web interface. If a customer already visited a paricular PPB installation their session will be detected automatically and PPB will open their trial site for editing.
